1. Open Registry Editor by navigating to Star Menu > Run ( on windows 7 search for Run in start Menu ) now type “regedit” and you will see your Registry Editor opened.

2. Now Navigate to the following path :


3. Now double click on the WriteProtect and make its value 0 and than click OK.

4. Now just close registry editor and restart your computer for changes to take effect, now plug your memory card or USB in and enjoy non write protected memory card.

Removing Write Protection Using Apacer Formatting Utility :

Now if you are not able to remove write protection from your Memory Cards or USB Drives using the above method than you can go for Apacer Formatting method which simply works quit good.

Now this method needs your card or USB Drive to be formatted so make sure that you have copied all the data from your USB Drive to your computer, now follow steps from below and have fun.

1. Download Apacer Formatting Utility to your computer, make sure its not kept inside the USB Drive just keep it anywhere outside where you can remember.

2. Now extract it and than plug your pen drive or memory card in to your computer and than double click on the Start.bat file present inside the folder you just downloaded. Now this step will start formatting your drive or card so let it do its work till you figure out that formatting is done.
